Express the following numbers in scientific notation: (a) 0.27, (b) 356, (c) 47,764, (d) 0.096.

(A) 2.7*10^-8, (B)3.56*10^2, (C)4.78*10^4 (D) 9.6*10^-2

Explanation:

Scientific notation is a system that allows you to express very large or very small numbers by multiplying them by multiples of 10 with positive or negative exponents

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

the answer is c.the valence of the atoms combine .
